Before InstallationIf you do not have the knowledge to install the thermostat safely then you must arrange for a competent electrician to install it for you. Wiring must conform to the current IEE regulations.

Prior to commencing the installation you must ensure the mains supply is switched off.

1. Installing the Digistat Receiver

1a. Location of the receiver

Location The Digistat Receiver should be mounted in a convenient

position, close to the boiler or central heating system wiring centre. (Care should be taken not to mount the receiver in a position where it is surrounded by metal objects or mains voltage cable, as this may interfere with the radio signal). For the best performance install in an open space, at least 30cm distance from any metal objects including wall boxes and boiler housing.

It is recommended that the receiver is mounted on the wall nearest the final location of the Digistat Thermostat room thermostat and not less than 30cm from the boiler side panel.Warning: Installing the receiver too close to the metal side panel or mains cables may interfere with the radio signal.

Installation Guide

1b. Installation of the wallplate

Fixing (minimum wallplate clearances shown below)i. Loosen the securing screws, remove the wallplate, and if

surface wiring is to be used, snap out the cable entry strip on the bottom edge of the wallplate with a pair of pliers.

ii. Fix the wallplate, terminals at the top, either direct onto theflat wall using wall plugs and no 6 x1” wood screws or on aflush-mounting single conduit box using M3.5 x 14 screws.

2. WiringThis product is double insulated and does not require anearth connection. The receiver should be wired to thecombi boiler or central heating wiring using the correcttype of cable or flex. The receiver should be wired in toreplace hard-wired room or programmable thermostatsshown on the system or boiler wiring diagrams. Alwayscheck other manufacturers’ instructions for compatibility.

Relay Output

3. Replace the front cover of the receiver by locating the twolatches at the top and then fasten the two screws at thebottom. As soon as the Digistat receiver has power it will beready for automatic pairing with the Digistat RF Thermostat.

4. Automatic pairing4a. Heating and Hot Water: when the Digistat Receiver is powered

and the Digistat Thermostat has batteries inserted both will automatically pair. While this short process is ongoing the receiver LEDs will lash green/amber and the thermostat will display the word SCAN.When the receiver is detected by the thermostat, the thermostat will display the options for the 2 channels:CH = heating onlyPress + or - button to change todHW CH = heating and hot waterCon irm your selection with the O button.Once paired the left-hand receiver LED will be solid green and the thermostat display will show the words PAIR REC for 3 seconds, before displaying current time and temperature.

4b. Two heating channels: irstly pair the irst Digistat Thermostat as above selecting CH on the Thermostat. The second Digistat Thermostat (part number RF90T supplied separately) is paired by pressing and holding the left-hand button on the receiver for 3 seconds and then inserting batteries in the new Thermostat. The Thermostat will display the word SCAN and the Receiver LEDs will lash green/amber. Once paired the right-hand receiver LED will be solid green and the thermostat display will show the words PAIR REC for 3 seconds, before displaying current time and temperature.

Installation and Quick Start Guide 06490311001 Iss A

To make changes to the default Installer Options shown below, enter the Installer Options menu by pressing the settings button for 3 seconds. This allows access to the User Menu 01, the Advanced User Settings Menu 02, the Installer Settings 03, and Service Interval Settings 04. Use the + and - buttons to scroll to Installer Options and press O to select. You can exit the menu by pressing until you have returned to the home screen. In the Installer Options menu (Fig 8), scroll through the options using the + and - buttons and press O to select. Scroll through the different settings using the + and - buttons and press O to select and save. (Fig 9 shows Option 02 OFF).

(Fig 8) (Fig 9)

(Option 01) Partial Sight AssistantWhen enabled, audible tones indicate when the setpoint is more than, less than or equal to the current room temperature when a user manually adjusts the setpoint using the + button: Setpoint > room temperature - single high tone per 0.5°C increase Setpoint = room temperature - double tone Setpoint < room temperature - single low tone per 0.5°C decrease

(Option 02) Frost ProtectionThe Digistat will switch on the heating if the temperature falls to 5°C and maintains a temperature of 7°C even when in OFF mode.

(Option 03) Minimum Setpoint LimitChange minimum setpoint temperature. After any changes to setpoint limits, all setpoints in AUTO, MANUAL, BOOST and HOLIDAY modes will be modified to conform accordingly.

(Option 04) Maximum Setpoint LimitChange maximum setpoint temperature. After any changes to setpoint limits, all setpoints in AUTO, MANUAL, BOOST and HOLIDAY modes will be modified to conform accordingly.

(Option 05) Optimum StartWhen enabled, this uses current ambient temperature, the next scheduled setpoint and heat gain data captured by the device to adjust the thermostat setpoint early, so the ambient temperature is at the required level when the next event starts.

Delayed StartWhen enabled, this uses current ambient temperature, current event setpoint and heating characteristics of the environment to delay implementation of the setpoint if the ambient temperature is already close to it, therefore saving energy.

(Option 06) Valve Protection TimeIn some hydronic heating systems it may be required to protect the valve by operating it for a given time. When enabled, this maintenance feature ensures that each relay output is operated for at least one (1) minute each week.

INSTALLER OPTIONS - continued

The Drayton Digistat thermostat is a universal thermostat with 24 hour, 5-2day or 7day program types and up to 8 time/temperature events per day and can also be used as a simple room thermostat.

Clock SettingYour Digistat is fitted with a “real-time clock”, which is pre-set at the factory; you will not have to alter the time settings. A special feature of this real-time clock is it will automatically change over during the GMT/BST summer/winter change-over, removing the need to manually alter the clock at these times.

General OperationProgrammable thermostats do not have “On” and “Off” times like traditional timers. They offer temperature control both day and night and you simply select which temperatures you require at each point in the day.

With the unit in “Auto Mode” (the calendar icon is visible at the bottom of the screen) the temperature can be changed for a short time by using the + and – buttons. Changing the temperature in this way will keep the Digistat set to your new temperature until the next pre-programmed event (at which time it will revert to programmed temperature). The temperature you are setting will flash on the screen. Once temperature is set, the unit will revert to showing the room temperature again. The indicator will show on the screen if the unit is calling for heat.

Programming the DigistatYour Digistat comes with the following settings pre-programmed for your convenience and is suitable for those working out of the house during a typical 9-5 pattern. When the 5-2day program type is selected the pre-set temperatures will be different Mon-Fri and Sat-Sun, as per the tables below:

Pre-set Program 1 (24h, 5-2day weekdays, or 7day):
